49-53 cam gear

[Randall]

Ordered a new cam gear 49-53 and the teeth are cut opposite of my original
gear anyone experience this?

[Zeke3]

The direction of thrust of the camshaft was changed on the 49-53 engines from the direction of the earlier model flatheads. So, either they sent you an early camshaft gear or your engine was built incorrectly with an early cam gear at some time.

Which cam gear does the crank gear match?.......Mark

[Randall]

Someone had early gears on a late block so I am putting the latter gears in
Thanks

Here's some really good info.

If your engine has the stock timing cover and distributor you need the late gear set. If it has been changed to the early distributor down front you must use the early gears.

Mine has the late dist.

I just disassembled a 49 8BA and it has the early gears in it. Is there a real problem with that? I know you can’t use the later gears on the early engines with the front mounted distributor.

Either gear set will work. Get a good set of either style of gears and you will be fine. My personal preference is an aluminum camshaft gear instead of fiber.
My understanding is Ronnieroadster has done testing and found that the helical gears driving the oil pump thrust the cam in the same direction regardless of the timing gears.

That is very interesting. I hope Ronnieroadster will provide more info. on his findings.

And then there are straight cut gears for those that want to go fast.

He has mentioned it at least two times on this forum, it got some discussion in this thread: https://fordbarn.com/forum/showthrea...0099&showall=1

THANK YOU 38 coupe for posting the link to Ronnie's research.
Very enlightening. Read every word.
